    Hello, for the past two days, Firefox is unable to display/open pdf files. I clicked on the links. The contents are not shown on the screen. Know how to fix this issue? Thanks.

    Possibly try this:

    Switch from the built-in PDF viewer to another PDF viewer:

    1. On the menu bar, click on the Firefox menu and select Preferences...
    2. Select the Applications panel.
    3. Find Portable Document Format (PDF) in the list and click on it to select it.
    4. Click on the drop-down arrow in the Action column for the above entry and select the PDF viewer you wish to use.

    Screen shot of it:
